1 Mini LED Spotlight Cut & Drill tubing Pieces ½ EMT Conduit Cut at 12 3/8 OD Copper Hard copper Tubing cut 3-1/2 long. Mark and drill a 5/32 hole for wire to pass through 5/8 from end. Take a large pair of pliers and position on the last ½ end of the copper with the hole in tube facing up. Squeeze and flatten the end of the tube. Take the drill and clean and ream the hole so the wire can pass through. Drill a 3/16 hole in the center of the flat portion of the tubing. Wire preparation Strip off outer jacket of the #22-2 conductor cable 1-3/4 to 2 from end. Strip off black insulation 1-1/4 from where the gray insulation was removed. Strip off Red insulation ¾ from where the gray insulation was removed.

2 Soldering Lay out LED, Resistor and wire so that they are 1-3/4 from the striped off gray insulation to the back of the LED (where the leads come out of the LED). Trim LED leads, wire and resistor leads so they will all fit in the 1-3/4 space when completed. BEFORE SOLDERING Slide the 1 long piece of 1/8 heat shrink over the Black wire. Solder the black wire to the negative side of the LED (lead on the flat side of the LED). Solder the 1/2Watt 300 ohm resistor to the Red wire and LED. Make sure the wires are not touching and test to make sure LED Lights and polarity is correct (+ & -). Slide the 1/8 x 1 long heat shrink up the black wire over the bare parts and shrink to insulate the black wire all the way to the base of the LED. Final Assembly Slide the ¼ 2 long piece of heat shrink over the led onto the wires that were soldered and shrink in place to insulate all bare parts so they cannot contact the copper tube. Tie a knot in the wire aprokimately 2 from the LED. Push cable into the end of the copper tube and out the hole near the base. With the knot in the wire about 2 from the end this should allow some adjustment for the placement of the LED in the tube. The farther back in the tube the les glare from the light and the narrower the beam. Leave the led flush with the end and the light will spread more. Attach the copper tube to the conduit clip with the #8-32 machine screw and nut.

3 Tools Saw to cut metal tubing, hack saw, jig saw or band saw with metal cutting blade. Drill, bits 5/32 and 3/16 Center punch or ice pick (makes drilling on tubing easier). Hammer Large pliers, channel locks or vise grips. Metal file, Small side cutters, metal tubing reamer, flat blade screwdriver (removing burrs on tubing). Soldering iron, solder and soldier s helper holder. Stripers or razor knife. Extension cord splitter Optional - Heat Gun, Torch, for heat shrinks. I will have a good heat gun and it only takes a few seconds to shrink the tubing.
